12 v wires in bed room celing
« on: May 20, 2018, 01:00:19 AM »
Hi In my 2005 Monterey Laguna III just to the right of the air conditioner intake in the bedroom there is a face plate and a behind it what looks like 12v power and ground ( red and black) I am thinking that these are for perhaps a ceiling fan? This would be nice because I would like to put one in. My dilemma is that I have no idea where they might go, or what they might be connected to.... or if someone has something similar?


Please advise.


Thanks Jim

Jim,
Ours is 2 years newer Contessa Laguna and the location you describe is our smoke detector.  Could be yours was removed or never installed? I’m not sure 12v is sufficient to power a full size ceiling fan but I could be wrong.

Have you experimented to see if red is always hot or if switched?

We also have a smoke detector there.  They do have 12v ceiling fans.  Not sure how they work but it would be nice to have one.

Jim,
I checked the 05 Monterey prints in Coach Assist and there are no AC boxes shown in the ceiling. I think you are right re 12v for fan. If junction box beneath plate has a wood frame around it, fan is probably the intended appliance. Is line hot now? if yes you'll be able to use remote for control. (I'd still locate source by pulling fuses, etc.) If no, you'll need to find source or check wall in bedroom for intended switch location and hot 12v line. Other possible use for the 12v line you located could be lights, but in past they used white wires for them.
Have fun.

I support Jerry's suggestion that it is the power supply for a smoke detector unless this is in addition to an existing smoke detector.

I'm with Jerry and Bob. Those wires are connected to a smoke detector in our Monterey Laguna IV.

Hi I hooked up to meter and it has 12v continuously and removed all 12v fuses in "House 12v fuse block" and it did NOT disconnect power. Apparently Beaver made a change in that my manual indicates smoke alarms are 9v battery operated only and no reference to fuse for those wires.  So for those that have 12v operated smoke alarms, can you tell me where your fuse for the smoke alarm is? I have to believe that it is on a fuse somewhere.
I want to check current rating before connecting ceiling fan. I am thinking that if the circuit if only for one smoke alarm the amperage on the fuse may be to small to support the fan. 

Thanks Jim

My CO/LP detector fuse is in the 12 VDC panel in the closet. #14 same circuit as the BR slide and Tstats. It is a 15 amp fuse. It has 3 wires, blk,red and brown.   I also have a fuse for ceiling fans but no fans, maybe fantastic fans.
Hope this helps.
Jerry

I’m inclined to think you may be seeing where a CO detector should be.  Ours is 12v. and to the curbside of the bedroom air conditioner unit.  It’s lamp is always on as long as the batteries main switch is on, so the wire would be hot... not sure if there’s a fuse other than perhaps one on it’s circuit board.

The smoke detector is over the dinette up front and uses a 9v battery.  The LP detector is floor level (propane is heavier than air) in the kickpanel below the kitchen sink.  I’m not sure the Monterey was prewired for a fan.

Opps, thank you Joel, contary to my previous post it is a CO detector over the bed. The smoke detector is in the same location mentioned by Joel, on the ceiling near the refrigerator.

I went out and looked, and stand corrected, just as Bob has posted.

Ok found it. Power is connected to breaker in the main distribution box along with the battery disconnect switches. It is connected to LP/BIRD BOOST circuit breaker. This breaker also powers the LP gas detector. and I assume bird and boost relay. Who would have thunk it but I suppose that it would keep power to the detectors even if coach 12v was turned off.

Looks a if it has enough to power a fan.

As An fyi for those who would like to install a fan, trusty products makes a wireless remote control fan so all that you need is 12v in the celing. no need for 12v to the wall switch and then multi wire cable to fan. part number is 70058NW

Jim, do you actually have that fan?  I looked it on line and it seems to indicate that you have to have a wall switch hooked up.  Apparently the remote just "talks" to the wall switch and not the fan directly.  When I took that CO detector down to check the battery I couldn't help but think those wires would be perfect for a fan.  Thanks
Jerry
On edit...different fan but question still stands.  Thanks

I have a ceiling fan in my 03 Monterey and there is no wall switch, only a remote to turn it on and off.

Hi Jerry I do not have the fan yet but here is the installation manual from Camping world web site. This shows the 12v only requirement. Best Jim
